/* Zorum v1 design system (ZS-DIS-01). Source of truth copied verbatim into web/chat/,
   web/platform/, web/admin/ by tools/build_ui.py -- edit only here.
   Palette/type follow the legacy web/chat.html sample; --muted and --amber are tuned darker than
   the legacy sample so text on --bg/--white/--soft still clears WCAG AA (>=4.5:1), verified by
   tests/test_web_backend.py::TokenContrastTests. --on-accent/--on-danger are the text color for
   filled --green/--danger surfaces (buttons, marks, error toast) -- white in light theme, dark in
   dark theme, because --green/--danger themselves flip from dark-on-light to light-on-dark
   (FIX-r01/R6: white text on dark theme's light --green was 2.22:1). No external fonts/CDN/icons:
   system font stack, inline SVG icons via ZorumUI.icon(). */
